摘　　要：人类髌骨可以用来鉴定性别,但在非人灵长类中,利用髌骨鉴定性别还未见报道.通过利用几何形态学方法对25例太行山猕猴髌骨标本进行研究,选取32个标志点/半标志点,通过主成分分析和判别分析,探讨太行山猕猴髌骨的几何形态差异.主成分分析散点图结果显示,雄性个体主要位于PC1轴大于0.03的部分,而雌性个体全部位于PC1轴小于0.03的部分,雄性标本的关节面比雌性标本更短、更宽.判别分析结果显示,利用髌骨判定性别的成功率在雌性和雄性猕猴中分别为100.0%和85.7%,证实了利用髌骨对太行山猕猴进行性别判定的可行性.Human patella could be used to identify gender,while in non-human primates,using patella to identify gender has not been reported.In this study,the patella shapes of 25adult Macaca mulatta from Taihang mountains were analysed using geometric morphometrics,and 32 landmarks/semi-landmarks were selected to investigate the geometric differences of patella by principal component analysis and discriminant analysis.The scatter plot of principal component analysis showed that the males were mainly located in PC1 axis greater than 0.03,while the females were all located in PC1 axis less than 0.03.The articular surface of males was shorter and wider than that of females.The results of discriminant analysis showed that by using the patella shape,100.0%of females and 85.7%of males could be correctly identified.This study demonstrates the feasibility of using patella to determine the gender of Macaca mulatta from Taihang mountains.
